Title: Incidence direction measurement system - is for electromagnetic waves and uses group of passive aerials connected via switches
Inventor: MEINKE HANS HEINRICH PROF DR
IPC: H01Q23/00
Filed: 1976-03-26
Abstract: An incident direction measurement device for electro magnetic waves, consisting of a group of passive aerial placed at different spatial positions and connected via conductor channels contg. connecting cables and switches to one or more receivers is designed to minimise switching transients, to remove the frequency dependence of the switched connector phase lag, and to reduce the accuracy requirement and the input impedance of the receiver. Electronic switches (Vn) between the antenna and their corresp. connection channel have constant time characteristics, are not operated by the control circuits, and have a high gain throughout the frequency range. The switches determine the receiver signal-to-noise ratio.

Title: Vertical batten magazine for stacking planks - has slider bar with gate blocks for regulating batten discharge
Inventor: RIGHI EDUARD
IPC: B65G59/06
Filed: 1976-09-06
Abstract: A vertical magazine frame consists of two parallel U-channel profiles (2, 3). The open side of the profiles face each other such that between them, a vertical stack of wooden battens (6) can be located. At the lower end of the frame, a slider bar (19) with gate blocks (11, 12), keeps the magazine frame normally closed. By moving the slider bar to one side, one end of the nearest batten is freed in order to drop out of the frame. When the slider bar is moved to the opposite side, the other end of the batten is able to drop out. Thus a controlled discharge from the vertical batten magazine is obtained.

Title: Metal packing for synthetic, coachwork trimming strip - is densified locally to overcome distortion and facilitate adhesion
Inventor: VOLLMER HEINZ
IPC: B60R13/04
Filed: 1977-01-15
Abstract: An ornamental strip, esp. an adhesive strip for the outer surfaces of automobile coachwork, consists of an extruded synthetic profile and on its bottom surface a metal strip which has been sheared along both its edges. The metal strip has in its central zone and running lengthways, a local densification produced by rolling. The densification consists of very shallow grooves running parallel to each other. These zones differ in the degree to which they are densified and in particular their densification diminishes across the strip and towards the edges. The metal strip has such a degree of flatness transversely, or has such a slight curvature, that the irregularity thus uniformly to the coachwork across its full width.

Title: Brake lights for model racing cars - use light emitting diodes activated reverse current generated by motor during deceleration
Inventor: WARNECKE WILFRIED
IPC: A63H17/28
Filed: 1977-01-27
Abstract: A model racing car is driven from a battery or other d.c. source. The motor (M) is connected to the battery with a diode (D1) in the positive line. Two light emitting diodes (D2) (D3) are connected in parallel to the diode (D1) but are conductive in the opposite direction. When the voltage regulator is brought to the null position the motor is short circuited and begins to act as a generator and generates a current which flows in the opposite direction. This current is blocked by the diode (D1) but flows through the light emitting diodes (D2)(D3) so that they are activated and operate as brake lights. An alternative circuit uses small lamps and one extra diode.

Title: Ternary liq. mixt. analysing appts. - measures physical parameters under two different conditions
Inventor: WEINREICH PETER
IPC: G01N9/00
Filed: 1977-03-15
Abstract: The procedure for determining the components of a ternary mixture by the measurement of simple physical parameters is suitable for gaseous, fluid or solid compounds and is based on the fact that nearly all materials exhibit different characteristics when measurements are made at, for example, different temperatures or different wavelengths. By measuring the density, for example, of a water-methanol-ethanol mixture at 10 deg. C and 20 deg. C values can be drawn in on a prism and concentration triangle. The horizontal lines representing the densities at 10 deg. C and 10 deg. C can be vertically projected downwards towards the concentration triangle. The intersection point in the triangle thus obtained corresponds to the concentration of the mixture.

Title: Explosive pressure bolt inserting tool - comprises tube with centred holes for insertable bolt with hammer powered by single charge
Inventor: VOLK KURT
IPC: B25C1/10
Filed: 1977-04-07
Abstract: The tool for driving bolts by explosive pressure is for one-time use. It is made from a round iron bar approximately 20 mm thick and 115 mm long, and comprises holes of varying sizes, centered in a lengthways direction, which constitute the discharge tube. The holes take the bolt to be inserted, a thrust bolt, a cartridge and a striker bolt.

Title: Acoustic orientation system for vehicle occupants - uses missile-shaped microphones on roof with pointed ends in direction of travel and coupled to amplifier of stereo loudspeakers
Inventor: WINTER KARL
IPC: B60R11/02
Filed: 1977-05-26
Abstract: A microphone is fixed to each front corner or the vehicle roof. The microphones are preferably missile shaped and point in the direction of travel. The sound picked up is amplified and fed to two stereo load speakers arranged in the vehicle interior. The result can be improved by the addition of two extra microphones mounted on the rear roof corners and pointing to the rear. For use with vehicles having poor sound insulation (motor cycles) head phones are used in place of load speakers.

Title: Evaporator of heat pump with parallel lamella - has ultrasonic transceiver for sensing icing and triggering deicer
Inventor: NEUMANN GOTTFRIED
IPC: F25D21/02
Filed: 1977-07-07
Abstract: The refrigerator evaporator which can be deiced has parallel lamella and sensor for evaluating the icing of the lamella.

An ultrasound receiver (7) is fitted on the other side of the evaporator. The transmitter and receiver are arranged on a line between two adjacent lamella (4). The wavelength transmitted is smaller than the spacing of the lamella. The obstruction of sound path caused by ice layer block sound reception and triggers deicer.
Patent DE-2731810-A1 (DE)
Title: Use of pyrolysis oil from scrap rubber, esp. tyres - after sepn. into low-and high-boiling fractions, as an additive to bitumen or solvent for plastics or rubber
Inventor: HOELL RUPERT
IPC: C08L95/00
Filed: 1977-07-14
Abstract: Pyrolysis oil from scrap rubber is sepd. into specific fractions, which are used for various purposes. Those boiling at >200 degrees C. are added to bituminous materials and may be used to swell or dissolve certain plastics before mixing with the bitumen. Fractions boiling at 200 degrees C. can be used to dissolve plastics or esp. rubbers to give solns. which can be vulcanised after addn. of sulphur or other suitable materials. Processing of the bituminous materials for roofing and sealing sheets, sound and heat insulating sheet, etc. is improved. Plastics can be incorporated into bitumen grades not previously suitable. Aromatic hydrocarbons can be extracted from the lower-boiling fraction, and it can be used like coal tar as a raw material for resins. In mixts. with bitumen, the high-boiling fraction reduces break pt. and hardness, increases elasticity, extensibility, ductility and adhesion, increases solubility of plastics, and shortens stirring times.
